TGOL FOR APPLYING PUTTY.

Application filed February 23, 1922. Serial No. 538,744.

To all 7.0710771- izf 11mg] concern.

Be it known that CHARLES H. WEBER, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio, hasinvented certain new and use tul Improvements in Tools for ApplyingPutty, of which the following is a specification.

This invention relates to a tool for compacting, forming and applyingputty to window sash frames and similar structures and has for itsobject to provide a cheap, convenient and compact tool for this purpose.

More specific objects of the invention will be made apparent by thefollowing description and the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of the tool for carrying and applying theputty.

Figure 2 is a longitudinal vertical section taken through the center ofthe tool.

Figure 3 is a transverse vertical section taken through the line 83 ofFigure 1 and looking in the direction of the arrows.

Figure 4c is an end view lOOkiIlg from the right of Figure 1.

The device comprises a cylinder 1 in which putty is placed, having atits forward end a reduced tapered trough shaped prolongation 2communicating with it. This prolongation of the cylinder at its smalleror discharge end is formed to have a triangular cross section so thatthe putty which is :t'orced therefrom will be adapted to lie in theangle between the window glass and the sash "frame. Fixedly mounted uponthe open side of the member 2 is a rigid metallic closure plate 8 havingan upwardly inclined terminal portion disposed in angular relation tothe member and is adapted to be pressed against the putty as it passesfrom the member 2 to force it firmly into place. The end of the cylinderis provided with a cap 1 having an opening 5 through its center. Apiston rod 7 carrying at its forward end a piston 8 passes through theopening in the center of the cylinder cap. The rear end of the pistonrod. carries a collar 9 which terminates in depending flanges 10 havinga spacer block 11 therebetween and at their lower extremities receivingbetween them the end of a rack bar 12. The collar and flange member isretained against movement relatively to the piston rod by a pin 13. Onthe lower side of the cylinder 1 there is provided a depending U shapedhousing 14L for receiving and guiding the rack bar 12. At its rear endthe cylinder is surrounded by a collar 15 which terminates in dependingflanges 16 that receive between them the rear extremity of the U shapedguide member 14: and immediately therebeneath a pinion 17 which isadapted to mesh with and actuate the rack bar. This pinion is mounted torotate with a shaft 18 having fixedly connected to its outer end a knob19 which is provided for the purpose of being grasped by the operatorand rotated to advance and retract the piston in the cylinder.

The operation of the device is as follows: it-h the piston and rackremoved from the cylinder unit, putty is placed in the cylinder. Therack is then loosely inserted in the U shaped guide and the piston headis loosely inserted in the cylinder. The operator then gives the knob aslight turn to mesh the pinion with the rack and with his hands forcesthe cylinder cap into place, when the device is ready for use, byadvancing the piston through a further turning of the knob.

It will be understood that by the provision of the guide opening for thepiston in the cylinder cap and the U shaped guide memher for the rackbar, all tendency of the sliding members to bend or get out of alignmentwith the cylinder is eliminated.

What I calim is:

1. In a tool for applying putty, a cylinder, a reduced trough shapedmember forming a prolongation of said cylinder and terminating in areduced forward end which is triangular in cross-section, a plateattached to said member and closing one side thereof, the outer end ofsaid plate being disposed in angular relation to the member, a piston insaid cylinder to compress the putty and force it from the forward end ofsaid member, and rack and pinion mechanism for operating said piston.

2. In a tool of the class described, a cylinder, a piston mounted toslide in said cyl inder, a rod for the piston, a housing on i the lowerside of said cylinder, adapted to act as a guide, a collar surroundingsaid cylinder having depending flanges lying on opposite sides of saidhousing, a rack con nected to said piston and received in said guide, apinion supported between the depending flanges and meshing with saidrack,

a forwardly extending rack connected to the 10 rear end of said pistonrod, and a pinion for IIIOVillf said rack, the relative lengths of thepiston rod and rack being such that the piston head may be movedrearwardly to forcethe cap from the cylinder by turn- 15 ing oi thepinion.

In testimony whereof I afiix my signature.

CHARLES H. WEBER.
